Launched by Nicholas Kristof and Sheryl WuDunn, the Half the Sky Movement has finally come to Facebook via a game of the same name. We first learned about the game last June, as big names like Intel, the United Nations Foundation, Frima Studio, and even Zynga have come together to raise awareness about "the issues facing women and girls around the world, and to provide the life-saving tools to empower them."

The Half the Sky Movement game follows fictional female characters that might be forced to change their way of thinking or living in order to better their own lives, the lives of their children, and more. Quests offer educational content, and for every quest that's completed, players are given the opportunity to donate real money to a matching cause (a quest about vaccinations may give players the chance to donate to a real world vaccination center, for instance). Play enough, and you'll unlock a sponsor gift for free, without actually spending any money.

Aside from quests, the Half the Sky Movement game comes with match-three mini-games, a light marketplace simulation, virtual volunteer opportunities and more. For more information, check out the Half the Sky Movement website, the trailer above, or simply play the game for free right now on Facebook.
